Don’t get excited: this is yet another variety of the Anytone AT-5888UV. They must be imitating the Baofeng way of doing things – one PCB, many enclosures to choose from. Manufacturer / re-branding location here. Alibaba page here.
Youtube video below, which shows the original (and poorly designed) Anytone microphone, different from the one in the picture. No price known at this point in time, but I don’t expect it to differ much from all the other incarnations.
